To those who have been sufferers from the locusts in New York this 

 year — in the event of a prospect of a recurrence of the visitation

 eaten by Julus cceruleocinctus from the surface of the ground down- 

 ward six inches to the seed tuber, burrowing into which were a num-

A similar attack is published in the Rural New Yorker for June 22, 

 1889 (page 416), where the stems were found fallen over and either 

 dead, wilted, or wilting. Investigation showed that a thousand-legged 

 worm was the cause. "In some instances the vine was girdled; in 

 others from one to four of these millepeds were found eating into the 

 stems; in others they had bored into and up the stem. The vines at
